OPERATING MECHANISM FOR VENTILATING WINDOWS.

Application led September 19, 1907. Serial No. 393,663.

To all whom tt tmay concern:

Be it known that I, STEPHEN E. CIBULAs, a citizen of the United States, residing at Bridgeport,. county of Fairfield, State of Connecticut, have invented a new and useful Operating Mechanism for Ventilating Windows, of which the following is a specification.

This invention has for its object to provide mechanism for operating a series of windows, as for example 'the Ventilating Windows of railway cars, in such a manner that every window in the series may be locked in the closed position or swung to the open position from either end so that every window can be made a ventilating window when the car is going in either direction.

It is of course well understood that in using end swinging windows for car ventilators, it is desirable that the end toward the direction in which the car is moving should be closed and the other end swung open, so that air will not be drawn into the car but air will be drawn from the car by suction. For example, if the car is moving toward the left, as seen in Figs. 1 and 2 of the drawings, the left ends ofY the Ventilating windows would be in the closed position and the right ends swung toward the open position. In many of the window operating mechanisms now in use, one end only of the windows can be swung to the open position.' This is all right when the oar is moving in one direction but is objectionable when the car is moving in the other direction as the windows must be kept'closed or opened but slightly and even then air will be drawn into the car bringing dust and cinders with it instead of being drawn out of the car as is required. The objections to a Ventilating system in Which the Windows swing in one direction onlyhave been partially overcome by the use ofoperating mechanism constructed to swing alternate windows from opposite ends, the first, third, fifth, etc. windows being swung to the closed position when the sccond, fourth, sixth, etc. windows are swung nto the open osition, and vice versa. important objection to this system is that only half of the windows in a series can bo opened at any time. My present invention overcomes the ob jections inherent in both of the above sys tems and providesoperating mechanism by means of which every window in a series .maybe swung to the open position from mediate the angle portions.

either end, thus providing efficient ventilation and exclusion of dust and cinders when the car is moving in either direction.

With these and other ob'ects in view I have devised the simple and novel window operating mechanism which I will now describe, referring tothe accompanying drawings forming a part of this specification and using reference characters to indicate the several parts:

Figure 1 is an elevation illustrating the application of my novel o erating mechanism to the Ventilating win( ows of a railway car, the windows being in the closed position; Fig. 2 a longitudinal section on the line 2--2 in Fig@ 1, looking'down, as indicated by ar,- rows, the position of the windows when swung to the open position from the left ond being indicated by dotted lines; Fig. 3 a detail elevation on an enlarged scale, showing the position of the operating mechanism when a window is swung to the open position from the right end; Fig. 4 a longitudinal section on the line 4 4 in Fig. 3, the window and the operating mechanism appearing in plan; Fig. 5 a vertical section on the line 5-5 in, Figs. 1 and 3, llooking toward the right as indicated by arrows; and Fig. 6 is-a vertical section on the line 6-6 in Figs. l and 3, looking toward the right as indicated by arrows.

10 indicates surrounding framework for windows, for example the body of a railway car, and 11 Windows swinging in openings 12 therein. Each Window is shown as provided at each end at its mid-height with an eye 13. These eyes are adapted to be engage'd by hinge pins 14 at the ends of rocker.

arms 15 which are pivoted in brackets 16 secured on the inner side of the framework intermediate the windows, an additional rocker arm and bracket being provided at the end of the series from which the windows are actuated. Each window is provided at its middength with a cross piece 17 to which a plate 1S is rigidly secured, said plate being provided with an angle slot 19 having a relatively short straight portion 20 inter- .Eaeh angle slot is engaged by an operating pin 21 carried by an operating bar or rod 22 which has its bearings in brackets 16. In the present instance l have shown the operating bar as an angle bar although of course the special shape of the operating bar in cross section is Wholly immaterial so far as the vprinciple moved toward the left from its midosition,

lstraight portions 20 of said slots.

of the invention is concerned. 23 denotes cams on the operating bar, each cam comprising a central high portion indicated by 24 and inclines25 at the ends of the high portions. These cams are enga ed by bearmg portions 26 at the ends o the rocker arms, for a purpose presently to be explain n'. The operating bar may be actuated in either direction to close all the windows in a series L or to open them from either end in any ordinary or preferred manner. I have shown the end of the operating bar as provided with openings 27 which are engaged by the teeth of a pinion 28 on an operating shaft 29 which is mounted to oscillate iny bearings 30 and is shown as provided with a hand wheel 31 for convenience inoperation.

The operation is as follows: When the operating bar is at its mid-positiom'operating pins 21 will be at the mid-length of straight portions 20 of angle slots 19, bearing portions 26 of the rocker arms Will'be in engagement respectively with the inclines 25, both of the hinge pins 14 on each rocker arm will be in engagement with an eye 13 at one end of a window and all of the windows in the series Will be in the closed position and locked there by the engagement of a hinge pin with an eye at each end of each Window. Sup ose now that itis desired to swing the windbws toward the open position from the right end, as shown in Figs. 3 and 4. The operator simply moves the operating bar toward the left as far as may be necessary to swing the Windows -to the desired open position. When the operating bar is the operating pins 21 will travel om the straight portions 2() of the angle slots down the left portions of said angle slots, as shown in Fig. 4. When the windows have reached their extreme open position, the pins will lie at the eXtreme ends of the angle slots. Should it be required to swing the windows toward the open osition from the left end, the operator wou dA move the operating bar toward the right, the operating pins 21 would then travel from straight portions 2O of the an le slots down the right ortions of said ang e slots until the win ows were placed at the required open position or until the ins had reached the ends of the slots. In c osing the series of windows, the operating ins travel from the angle slots to the A continuation of the movement of the operatinor bar will cause the operating pins to travel into the other portions of the angle slots and Will swing the Windows to the open position from the opposite ends.

It will be noted that the hinge pins 14 are made long enough and the eyes 13 are so placed on the window frames with relation to said pins that in the closed position of thewindows the eye at each end of each window will be engaged by a hinge pin, the

rocker arm standing horizontally, as in Fig.

yof the windows so that there is no time at which any window is not engaged by one of the hinge pins and is also retained in an position in which it may be placed throug the engagement of the operating pins with the angle slots in plates 18, the same being true of course when the operating bar is moved in the opposite direction and the left hinge pins are disengaged from the right ends of the Windows leaving the ri rht hinge ins engaged with the left ends o the win( ows so that the windows may be swung to the open position from the left end.

Having thus described my invention I claim:

1. Operating mechanism fora plurality of windows, comprising eyes for attachment to the respective ends of windows, plates having angle slots for attachment to the midlength of Windows, rocker arms to be pivoted intermediate the Windows and having at their ends hinge pins and an operating bar r and when the bar is moved in either irection tilt the rocker arms and disengage one hinge pin on each rocker arm from an eye, leaving the other hinge in engaged, the operating pins causing all t e windows in the series to swfilng to the open position from'the engaged. en

2.
